League of Legends is one of the most popular team-based action-strategy game developed and published by Riot Games.

The idea is simple - two five-player teams play against each other and the one that first take down the other’s base claims victory. Tons of decisions need to be made on battling, resource seizing, etc., and there are over a hundred characters (called ‘champions’) with distinct abilities can be chosen from, which make the game even more complex.

The map of a League of Legends game consists of Top, Middle, Bottom Lane, and Jungle. Five players from each team would choose which position they play at, usually 1 for Top, 1 for Mid, 1 for Jungle and 2 players go to the bottom.

For the two graphs, blue represents DWG and red represents Suning. We can see that:

Now let’s talk about champion picks!

The two networks demonstrate Suning and DWG’s top 20 picked champions in 2020 and how those champions are connected with each other (be in the same game). The thicker an edge, the more frequently the pair of champions be in the same game. I highlighted the most salient connections (red: mid to top, green: mid to bottom, blue: bottom and support, beige: others). We can have the following observations:

Bye Bye Season 2020, See You in 2021!


Now the League of Legends Season 10 has ended and the new season is right around the corner, I collected the last 7-day tweets with hashtags #leagueoflegends and #preseason and created this word cloud.

Looking forward to the new season and more games:)
